What is the contrast of the plot and sub-plot in Act I, Scene 1 and Scene 2 in "King Lear"?

Although both the plot and the sub-plot center around the relationship between a father and his children, there are many differences between the two.

Edmund, however, is more proactive. He begins to immediately plot his brother's downfall, showing himself not just the beneficiary of a twisted situation, but the instigator of it.
